Name: Dendrochilum cobbianum Rchb.f.
Synonyms: Platyclinis cobbiana (Rchb.f.) Hemsl.; Acoridium cobbianum(Rchb.f.) Rolfe
Etymology: cobbianum = named in honor of Walter Cobb, a 19th-century British orchid enthusiast and collector.
First description: 1880 by the German botanist Heinrich Gustav Reichenbach (Rchb.f.) in the Gardeners' Chronicle.
Origin / Distribution: Philippines (endemic to the islands of Luzon and Mindanao).
Location / Habitat: Growing epiphytically or lithophytically in montane cloud and moss forests at altitudes of approx. 1,200 to 2,400 meters. There, it colonizes shaded to semi-shaded locations on mossy tree trunks or rocks with high year-round humidity and cool to intermediate conditions.
Description & Notes: Dendrochilum cobbianum is a medium-sized, very vigorous orchid that forms dense, impressive clumps over time. It has conical-ovoid, glossy green to yellow-green pseudobulbs, each bearing a single, upright, lanceolate, and leathery leaf. The long, slender, and elegantly arching inflorescence develops from the tip of the new growth. It bears up to 50 small, star-shaped flowers arranged in two rows, which are white to cream-colored and have a contrasting, bright yellow to orange lip. During the day, the flowers emit an intense, pleasantly sweet fragrance (often compared to hay or honey).
In cultivation, this highland species requires year-round intermediate to cool conditions with a distinct nocturnal temperature drop. The substrate (e.g., fine to medium bark mixed with some moss) must be kept constantly moist during the active growth phase in summer and must never dry out completely. High humidity of over 70% as well as constant, gentle air circulation are essential to ensure healthy growth and prevent fungal diseases on the leaves.
